Connector having waterproof function and electronic device using same

Abstract

A connector is fixed in an opening of a housing of an electronic device. The connector comprises a main body housed in the opening, a gasket and a securing member. The main body comprises a plug portion, and an engaging portion connecting the plug portion. Furthermore, an engaging groove located on the engaging portion adjacent to the plug portion. The gasket located between the between the plug portion and the housing. The engaging portion sequentially passes through the gasket and the opening to make a part of the engaging groove away from the plug portion is located a side of the housing. The securing member partly engaged in the engaging groove and sandwiched between the engaging portion and the housing to fix the main body to the housing.

What is claimed is: 
     
       1. A connector fixed in an opening of a housing of an electronic device, the connector comprising:
 a main body housed in the opening, the main body comprises a plug portion, an engaging portion connected to the plug portion and forming an engaging groove adjacent to the plug portion; 
 a gasket located between the plug portion and the housing; and 
 a securing member configured for fixing the main body to the housing, the securing member comprising a base portion and two arms extending from the base portion, the two arms are partly engaged in the engaging groove; 
 wherein the engaging portion sequentially passes through the gasket and the opening to make a part of the engaging groove away from the plug portion is located a side of the housing and the securing member partly engaged in the engaging groove and sandwiched between the engaging portion and the housing to fix the main body to the housing. 
 
     
     
       2. The connector of  claim 1 , wherein the gasket is elastic and made of a waterproof material. 
     
     
       3. The connector of  claim 1 , wherein the engaging groove recessed from part sidewall of the engaging portion. 
     
     
       4. The connector of  claim 1 , wherein a gap of the engaging groove exposed out of the housing is less than the thickness of the securing member. 
     
     
       5. The connector of  claim 1 , wherein the two arms are extending from the same side of the base portion and parallel to each other. 
     
     
       6. The connector of  claim 5 , wherein an inclined surface is disposed on each of the arm away from the base portion. 
     
     
       7. The connector of  claim 6 , wherein the securing member is elastic and made of a rubber material. 
     
     
       8. The connector of  claim 1 , wherein a projecting portion is formed on each arm by the arm engaged in the engaging groove partly bend upwardly. 
     
     
       9. The connector of  claim 8 , wherein the securing member is elastic and made of a metallic material. 
     
     
       10. An electronic device comprising:
 a housing defining a opening; 
 a main body housed in the opening, the main body comprises a plug portion, an engaging portion connected to the plug portion and forming an engaging groove adjacent to the plug portion; 
 a gasket located between the plug portion and the housing; and 
 a securing member configured for fixing the main body to the housing, the securing member comprising a base portion and two arms extending from the base portion, the two arms are partly engaged in the engaging groove; 
 wherein the engaging portion sequentially passes through the gasket and the opening to make a part of the engaging groove away from the plug portion exposed out of the housing and the securing member partly engaged in the engaging groove and sandwiched between the engaging portion and the housing to fix the main body to the housing. 
 
     
     
       11. The electronic device of  claim 10 , wherein the gasket is elastic and made of a waterproof material. 
     
     
       12. The electronic device of  claim 10 , wherein the engaging groove recessed from part sidewall of the engaging portion. 
     
     
       13. The electronic device of  claim 10 , wherein a gap of the engaging groove exposed out of the housing is less than the thickness of the securing member. 
     
     
       14. The electronic device of  claim 10 , wherein the two arms are extending from the same side of the base portion and parallel to each other. 
     
     
       15. The electronic device of  claim 14 , wherein an inclined surface is disposed on each of the arm away from the base portion. 
     
     
       16. The electronic device of  claim 15 , wherein the securing member is elastic and made of a rubber material. 
     
     
       17. The electronic device of  claim 10 , wherein a projecting portion is formed on each arm engaged in the engaging groove by the arm partly bend upwardly. 
     
     
       18. The electronic device of  claim 17 , wherein the securing member is elastic and made of a metallic material.
